I purchased my 2017 infiniti q50 as a certified dealer owned vehicle with 4710 miles on it from airport infiniti on 12/31/2018. since taking possession of the car, i have had three separate instances where my car lost power during acceleration, in which one of the instances nearly caused me to be hit by a semi-truck when crossing a divided highway. i have provided videos to the manufacture but they have refused to take action because the vehicle does not set any dtc codes. when this condition happens my 3.0t q50 accelerates extremely slow even with 100% throttle. the net result is that when i intend to cross a divided highway, i experience a 1-1.5 second delay from the time i push down the accelerator to when the car begins to move, then the acceleration from 0-15mph can take upwards of 5-6 seconds. the resulting feeling is a car that rolls into a dangerous intersection and exhibits stall like conditions. only once did the car set dtc codes during this instance. the codes set were b130d, c1a16 and po340. these codes set the first instance, but have not set during the past two occurrences of the same acceleration issue. these instances are completely random which make them extremely dangerous. for instance, the car will be driving completely normal, i will stop and an intersection and then when i go to turn out into the intersection, i go into this stall condition without warning. the dealership has had the car 4 separate times and each time they have refused to fix anything on the car, despite having a video of the occurrence and confirming that the acceleration was entirely abnormal. i have no choice but to drive this car if infiniti refuses to fix it, but feel it is likely that it will cause injury or death to me and my family if i drive it. i have attached a summary of the daily log i have been keeping since i purchases the car on 12/31/2018.
I purchased my 2017 infiniti q50 on october 06 2018 from carvana llc. the vehicle was used and had approximately 38k on the odometer. within 2 weeks of owning the vehicle the rear brakes pads need to be replaced and the rotors needed to be resurfaced. this was expected due to the high mileage on a 1 year old vehicle. then on january 11th 2019 i took my 2017 infiniti q50 in for its oil change at 43,000 miles with glendale infiniti in glendale california. when the service was completed the service advisor had notified me that my rear brake pads where at 4/32's and would need to be replaced within 6,000 miles. i had the brake pads replaced with the factory recommended brake pads at firestone in alhambra on 6 october as stated above. i did take the car back to firestone in alhambra ca for squealing brakes mid december 2018 and it was also discovered that the front brake pads needed to be replaced along with the rotors needing to be resurfaced. the rear brakes now squeal and will need replacement for the 2nd time in less than 3 months. my car is used to drop my son off at daycare and my wife at work and then to pick them both up and some occasional travel and work for my part time job as a rideshare employee which total 859 miles in december. i have seen complaints from other owners about having the rear brake pads wear prematurely. i ask ed the service advisor with glendale infiniti about it and he simply stated it is due to harsh braking. i responded with is that so because they where replaced with factory brake pads in october 2018. since the find the squealing is intermittent when coming to a stop and my stopping distance has increased even at low speeds on city streets.
